Electrical Connector for Large Conductors

The Burndy KSA500 split-bolt connector joins aluminium or copper conductors ranging from 400 to 500 kcmil on the run side and 2 AWG to 500 kcmil on the tap side. It is built for industrial and utility power distribution where high-current splices or taps are required.

Tin-Plated Aluminium Body with Square Head

The connector body is aluminium with a tin-plated finish and uses a 2-inch hex nut on a square head for installation. It accepts the stated wire sizes directly and requires a torque of 825 in-lb to secure the connection without additional specialised tooling beyond standard wrenches.

Rated for 35 kV and 194 Degrees F

The unit carries a maximum voltage rating of 35 kV and a maximum operating temperature of 194 Degrees F. It complies with RoHS requirements and meets CSA, UL 468A, UL 486B and UL 486D standards for safety and performance in permanent installations.

Questions about this item

What is the maximum continuous operating temperature for the KSA500 connector?

The connector is rated for a maximum operating temperature of 194 degrees Fahrenheit.

How much heat does the tin-plated aluminum body generate under full 35 kV load?

The connector does not generate heat itself; temperature rise depends on the current carried by the 400 to 500 kcmil conductors and the quality of the 825 in-lb torqued connection.

What conductor sizes and tools are required to install this split-bolt?

It accepts run conductors from 400 to 500 kcmil and tap conductors from 2 AWG to 500 kcmil in aluminum or copper, and requires a tool capable of delivering 825 in-lb of torque to the 2-inch hex nut.
